I drive BMW's because they hold lots of luggage, if needed, go like stink, if needed, are a decent value for the performance given and are very reliable.
My brother drives a Boxter because it is cool and girls look at him when he drives around campus. He doesn't care that it is temperamental, impractical, expensive to fix and overpriced.
Two different markets that really don't overlap except maybe in performance. Let Porsche do their thing and BMW do theirs.
End of arguement.
